Jquery localscroll question about vertical and horizontal scrolling


I have created the following page http://kylehouston.com/testing/localscroll/ where I have a number of main links and then sublinks for these. At the moment when a main link is clicked the content scrolls vertically and when a sublink is clicked eg Blue Inner Link 1 the content slides horizontally.

My question is how can I update the script so that when I click a main link the content scrolls horizontally and when I click a sublink the content scrolls vertically?

All advice is appreciated

Thanks Kyle

No script update is needed. Just position the content so that the main links are in rows, and the sublinks are in columns.
